The first trick here is a cut and restored trick that is fairly easy and one of the the most common
ways to do it. This doesn't mean it's bad! With the right story it can be a truly magical moment.
The second trick is a real puzzler and while it is less direct than the first, it's also a
solid trick that's easy for an audience to understand.
Some of the later tricks I didn't
care for -- I don't think they are direct or effectual enough to be worth doing like this. The
topological trick seems like it would be great to do with kids. The final trick is direct enough but
you need to go for your pocket a bit too often.
If you have good patter for these tricks
they will be more than just riddles, but create great memories as well.
